Triumph Daytona 660 engines can fail from disrupted oil flow

Triumph is recalling certain 2024-2025 Daytona 660 motorcycles because the engine may fail due to internal damage caused by a disruption of oil flow.

What this means for you

Illness, injury, or structural failure has been reported. Stop using the product immediately and contact the manufacturer for a refund or repair.

Our severity reasoning: Rubric level 4 covers structural vehicle defects: internal engine damage from oil starvation is a structural failure, and engine failure on a motorcycle removes propulsion while riding.
